Regular polygons are symmetrical. a) even- sided b) odd- sided c) rectangular d) all

Step-by-step explanation:

We have to find which type of Regular Polygons are symmetrical.

Regular Polygons are the polygons whose all sides and angles are equal.

For ex:- Equilateral triangle is a regular triangle as its all sides are equal and all angles are equal to 60°.

Square is a regular quadrilateral whose all sides are equal and all angles are equal to 90°.

Option A:

Even-sided  regular polygons are the polygons whose no of sides is an even no.

ex, quadrilateral with 4 side, hexagon with 6 sides.

They are symmetrical which no of line of symmetry equal to no of side.

Option B:

Odd-sided  regular polygons are the polygons whose no of sides is an Odd no.

ex, Triangle with 3 side, pentagon with 5 sides.

They are symmetrical which only 1 line of symmetry.

Option C:

Rectangular regular polygons are also symmetrical.

Therefore, Option D is correct .i.e., ALL regular polygons are symmetrical.

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
